TO ALL WHOM IT MAY CONCERN:

Be it known that I,` RALPH S.' JENNINGS, of the city, county, and State of New York, have invented a new and usefulginprovement in Envelopes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saule, reference being had to the accompanying drawings, forming part of this specification,- in Which- Figure 1 is a. plan view of the pattern of my improved envelope.

Figure 2 is a view ofthe same when partly folded and `joined together.

Figure 3 is a view of the saine when complete, ready for use; ,and

Figure 4 is a closed envelope. v

Similar letters of reference indicate like parts.

This inventionl relates to improvements in the construction of llat envelopes, which are more particularly designed to be usedlfor transmitting money and valuable documents safely by express and the mails, and consists in cutting the pattern and forming the envelope in such manner that the corners or ends under the top flap are closed by wings or counterfolds thereof, which are united with and form continuous parts ofthe central folds which make one side of the envelope; and further consists in joining the ends of the said central aps by means of metal rivets or spurs, which clinch and bind them together securely. The corner wings prevent the introduction of a wire or other instrument into an .envelope by which rogues often abstract money and valuable papers from envelopesof ordinary construction; and the unionoi` the central laps with metal rivets is for the purpose of dispensing with gum or paste entirely in the construction of the envelope.

Figure 1 represents a pattern of roy improved envelope as Icut out of paper or other material ;l the parts forming the sides and iaps being marked oand distinguished by dotted lines a a, running longitudinally, and b 6 transversely, which lines a a and b b are the creases or folds, made in the ordinary manner, for uniting the several parts of the envelope; of which A is the Hap which is'left free when the envelope is made; B the back; C C central flaps which are folded over andnnited with laps at their ends, as shown in fig. 2; and D is the top which is folded over upon and fastened to the central ilaps C C. The creases or transverse lines of folding Zz b are made a short distance within the corner ends of the ilap A. and the top D, intersecting `the lines a a atie so as to form corner wings E E outside of the lines a c b, at each end of the envelope, when it is folded and formed as shown in figs. 1, 2, and 3. The central folds C C overlap each other, andthe laps are fastened together by double metalspurs d 0l, which pierce through them from the inside and are clinched on the outside, as shown in fig. 2, and the top D is fastened down to the central ilaps C C with the eyelet-hole seals e e, or metallic envelope seals, for which Letters Patent were granted to me June 26, 1866. The Hap A is provided with the caps or heads c"e of the eyelet-l1ole seals e e, placed in corresponding positions for the purpose of closing and securing the envelope, as shown in iig. 4.

Having thus described my invention, and the manner of carrying the same into effect, I claim as new, and desire to secure by Letters Patent 1. In constructing flat envelopes, cutting and folding the same to form corner Wings E E at-the ends thereof, in combination with the eyeletJ seals e c', substantially in the manner and for the purpose herein described.

2. Fastening central ilaps C C of an envelope with the double metal spurs dd, or their equivalents, as

and for the purpose herein specied. I

RALPH S. JENNINGS.
